abnormal boost drops at 6k

im having a rare problem ive never seen anyone face before i dynoed the car previously and the boost was fine but i guess from the load change on the street the boost would die off 6k but not normal it would drop from 21psi to 11 12 psi. i have a aem tru boost in the car and changed the solenoid twice still the same problem i also changed the tb seals and injector seals the car is pretty much stock other then the mods listed below

Boost falling to 11 I think is the computer going in safe mode. Someone correct me if I'm wrong, but either your lines are hooked up wrong or maybe you have a boost leak!

i did a boos leak test it was fine someone told me of a rare problem with the boost controller if it doesnt get enough voltage that could be the problem with regulating the boost under a more load does that make sense im going to check it today

you changed the oem boost control solinoid (under the intake area)? You did a vaccum test? How did you do it? And lastly did you just get your numbers or did you get tuned on the dyno?

If you changed the stock boost solinoid, you tested for vaccume correctly and it didn't fix the problem then you should talk to your tuner.
